Orion is the only other choice. And to be fair, Safari with content blockers works fine too; but obviously it’s not an in-built adblocker that you are specifically asking.
Brave works really well for blocking on iOS. At least is has for me for quite some time. And Orion is another solid option. If I could get Floccus extension to work properly with Orion I'd probably switch completely.
DuckDuckGo works fine for me, it checks most of your boxes. Not sure about the ad blocker, but I run a pi-hole on my home network so I don’t see most of them anyway.
Not an expert but Duck Duck Go browser is decent afaik. Happy to be corrected though. Brave browser is one I use a lot too but I think it has some AI stuff now, though I believe you can turn it off
